So if anyone wants a tl;dw:
Guy goes and stands in the main area in front of a few trucks waving his sign. They honk, but it's unclear whether they are just honking, or honking at him. Probably both. He stands around like a goon and is mostly left alone by everyone who is clearly just having a good time. A cute canadian chick gets in his face and tells him to get fucked but doesn't do any more than that. A couple other folks approach him and honk at him with a clown horn for a bit. After a bit more standing around the video ends.
Watching the video compared to his writeup:

shows two extremely different narratives.
